    摘要: A smoking article including a wrapper surrounding a tobacco column and a selective filter element is disclosed. The selective filter element includes at least one carrier having a developed structure and a plurality of moieties capable of the nucleophilic attack of carbonyl-containing combustion products of the smoking article supported by the at least one carrier. The selective filter element may include at least one additional filter element such as cellulose acetate. The developed structure of the at least one carrier encourages the interaction of the carbonyl-containing combustion products and the plurality of moieties capable of the nucleophilic attack. Carries include polymers, which may have branch, such as partially oxidized cellulose and polyaniline. Carries may also be a zeolite or an inorganic oxide such as aluminum, of silicon, of aluminum and silicon, and combinations thereof. In yet another carrier is an activated carbon. A moiety capable of the nucleophillic attack includes a nitrogen and hydrogen containing group such as a hydrazide—(e.g., —NH—NH2), a hydrazone—(e.g., —HC═N—NH2), a semicarbazide—(e.g., —C(═O)—NH2), an imino—(e.g., —HC═NH), and an amino—(—NH2). Preferably, the nitrogen is a primary nitrogen such as a primary amino. A spacer may be used to attach the moiety to a carrier. Examples of spacers include at least one of a —CO— group, —CO—[CH2]n—CO— group with n=1 through 4 and more.

    摘要: A method for imparting reduced ignition propensity properties to a smoking article by treating the smoking article wrapper with a phase transition substance which, upon being subjected to the heat of the smoking article burning firecone, physically transforms and at least partially fills the pores of the smoking article wrapper to reduce the permeability of the wrapper in the vicinity of the burning firecone. The reduced permeability of the wrapper in the vicinity of the firecone will permit sufficient air flow to sustain free burn, but, when the smoking article is placed on a substrate, the reduced permeability of the wrapper imparts reduced ignition propensity such that there is insufficient air flow to sustain combustion of the firecone or insufficient air flow to sustain an intensity of the burning firecone necessary to ignite the substrate.

    摘要: Method of applying phase transition substance to impart reduced ignition propensity to a smoking article comprising a tobacco column and a wrapper surrounding the tobacco column and having a porous structure with a base permeability. The method comprising forming a pattern of phase transition material on the wrapper such that, when subjected to the heat of the tobacco column burning firecone, the phase transition material at least partially fills the wrapper porous structure in the vicinity of the burning firecone to form an area on the wrapper having reduced permeability lower than that of the wrapper base permeability. The reduced permeability of the wrapper in the vicinity of the burning firecone imparts reduced ignition propensity such that there is insufficient air flow to sustain combustion of the firecone or insufficient air flow to sustain an intensity of the burning firecone necessary to ignite the substrate.
